. .~ <br />~~ <br /> <br />MINING AND RECLAMATION PLAN <br />MT. GUNNISON NO. 1 MINE <br />4.5.6 ReveRetation Maintenance <br /> <br />October, 1979 <br />Revised January 30, 1981 <br />Revised March, 1981 <br />Revised October 29, 1981 <br />Revised November 18, 1981 <br />Soil erosion may be controlled through the use of mulch, matting, chemical <br />stabilizers, or other appropriate techniques. Gullies will be filled and stabilized. <br />During revegetation, maintenance activities will be conducted parallel to the <br />contour unless such activities prove hazardous to equipment and/or operators. <br />Then grading will be done by working upslopes or diagonally across the slope. <br />Mulch will be used where needed after planting to control erosion until vegetation <br />is established. <br />Bare patches of failed planting will be prepared and replanted. Where there is <br />evidence of poor soil' conditions, the area will be retreated or the topsoil replaced <br />as conditions dictate. <br />Attempts will be made to control noxious weeds during reclamation by mowing or <br />other appropriate methods approved by the Division. <br />4.5.6.1 Riparian Areas <br />Certain facilities will be constructed within the l00 Soot riparian buffer zone <br />identified in Figure 4.5.6.1. Such facilities include the water intake gallery, <br />sediment pond overflow ditches, railroad siding, and railroad loadout facility. <br />Within Section 9 T13S R901V the 100 foot wide riparian buffer zone encompasses <br />11.9 acres along the north and south shorelines of the North Fork Gunnison River. <br />Of this total acreage only 1.2 acres is covered by riparian vegetation; the <br />remainder is rock debris and an industrial area as depicted in Exhibit 2.3.5.C. The <br />total disturbance within the riparian vegetation cover area amounts to Yo acre. See <br />Figure 4.5.6.1 for details. <br />4-24 <br />
